A 14-year-old Maine ballet dancer who led a crusade against altered photos in Seventeen magazine now has a promise from top editor Ann Shoket to leave body shapes alone, reserving Photoshop for the stray hair, clothing wrinkle, errant bra strap or zit.

And when Shoket or her staff do manipulate images, she vowed in the August issue, they’ll post before and after shots on the magazine’s Tumblr page for full transparency.

Shoket’s promises are included in a “body peace treaty” that also commits the magazine to always feature healthy girls and models regardless of clothing size.

The young activist, Julia Bluhm, said Friday from her summer camp she’s “really excited.”

“I didn’t think it would get this big,” she said. “It’s a really great surprise for me.”
